Body count keeps rising as brutal bombardment of Aleppo shows no let up

Syrian government air strikes on rebel-held neighbourhoods of divided second city Aleppo have killed at least 15 civilians, including children.

More than 600 Russian and Syrian government airstrikes have hit Aleppo in the last six days, leaving a bloody body count of 126, the BBC reports.

Video purportedly showing terrifying Russian missiles raining down on Aleppo has been posted on Live Leak this morning.

Dozens of flaming explosives drop in clusters from the night sky, and streets are later seen alive with fire in the video.

The Syrian Observatory for Human Rights said at least 10 of the dead came in raids just outside the Al-Bayan hospital in the Shaar neighbourhood.

Two children were among four people killed in strikes on the Al-Marja district using barrel bombs -- crude explosive devices packed with shrapnel and usually dropped from helicopters, the Observatory said.

Rescue workers - known as the White Helmets - gave a higher toll of 23 dead.
